That night, while sleeping in Eric's room for a bet, Brian hears a loud noise, the source of which quickly disappears under Eric's bed. Brian subsequently is unable to make it through the night in Eric's room, making his way to the downstairs couch for the remainder of the night. The next morning, Eric and his friend Todd find Brian on the couch and joke about Brian being unable to sleep the entire night in Eric's room. Brian bets Eric "double or nothing" to sleep in Eric's room another night. The next night, a determined Brian sets booby traps, leaving bait in the form of cheese Doritos to attract the alleged "monster" and alters the legs on the bed to collapse once he determines the monster has come out from under the bed. He succeeds with this method, trapping the monster intruder: a blue-skinned monster named Maurice. Though scared and startled at first, Brian soon discovers that he and Maurice share the same interests and befriends him. Over the course of several nights, Maurice shows him a fun time in the monster world beneath Eric's bed. It consists of every child's dream: all the junk food and video games they want, and no adults to tell them what to do. It also has innumerable staircases leading to the spaces beneath children's beds, from which the monsters cause trouble. Maurice and Brian have fun making mischief in other people's homes, and Brian feels he has found a true friend at last; although Brian seems to be changing.
